For example, if you’re configuring a Content Grouping for Clothing identified by the Index Number 1, and within that creating a Content Group called shoes, you would update your config to have the following:

​gtag('config', 'GA_MEASUREMENT_ID', {
'content_group1': 'shoes'
}

For each content_group call, you can identify only one Index Number - Group Name pair.

Once you have updated your pages with gtag.js, those pages are then grouped according to how you identified them by index number and group name.

If you call the same index number multiple times on the same page, then only the last call for that index number is sent to Analytics.

Click OR or AND to add an OR or AND condition to the rule. Follow the instructions above to define the additional condition.

When you have defined all the conditions you want to use, click Done.

After you finish all your configuration for the group, click Save.

Naming: case sensitivity and effects on historical data

Case sensitivity

Content Group names are not case sensitive. For example, if your rule defines a content group as:

Page exactly matches /Google+Redesign/Apparel

then that rule will match any form of that page name. For example:

/Google+Redesign/Apparel

/Google+Redesign/apparel

Effects on historical data

If you change the name of a Content Grouping, there is no effect on historical data: all data will immediately appear under the new name of the Content Grouping.

If you change the name of the rule that defines a Content Group, then data from that point forward appears under the new Content-Group name, and data from before the name change appears under the old name.
